Logic fallacies are a tool for the foolish and recognizing them is your only defense.
Logical fallacies are dangerous because people can use them unintentionally or worse intentionally because their argument is poor. Critical thinking and logic are inseparable, but I would argue that one cannot think critically without understanding logic.
This page lists common logical fallacies and gives examples. I plan on adding to this list until it is complete.
Occurs when someone states a fact, then states something would be true if the stated fact were not true without other evidence.
A causes B
A is true
Therefore, B is true
Fallacy: Therefore, if counterfactual A was false, then counterfactual B would be false
A is true
B is true
Fallacy: Therefore, if counterfactual A was false, then counterfactual B would be false
Counterfactual: a conditional statement the first clause of which expresses something contrary to fact, as “If I had known.”
Example: My cousin died of covid, but he would not have died if he were vaccinated.
Cousin died
Vaccines reduce the chance of death
Fallacy: My cousin would have lived, if he had taken the vaccine.
This is literally unknowable
